Ive got a trek 69 hard tail and im wanting 2 up the size of the brake disks, now ive found they do disks up 2 203m which is what i want but a couple of questions!
does having the same size disks on the front and the rear a good thing or is it like a car where u want more brakeing at one point??
also how would u fit bigger disks using the same caliper? ither space the caliper out with washers or can u buy new caliper brackets that push them out more ?? (ive looked but can seem 2 find any??)

o buy the way my brakes are Avid Juicy !!

cheers in advance guys!
